In the Fairlight page using automation to record changes in levels for individual tracks. Lets say we have a music track which we set the level for using automation and a fader. Half way through there is a sound effect on another track so we set in and out point around that section so as to be able to loop and listen and adjust the level of the effect. The music is then played at the original level, not the level set by the fader using automation

i.e the playback doesnt take and prerecorded automation level into account when playing back a section of a longer audio clip.
